A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 9 m and a depth of 1.5 m. Suppose water is pumped out of the pool at a rate of 19 m per hour. If the pool starts completely full, how many hours will it take to empty the pool? Use the value 3.14 for a, and round your answer to the nearest hour. Do not round any intermediate computations.
